Why open architectures matter in defense programs 


Modern defense systems age fast. Sensors, processors, radios, and software evolve on their own timelines, and programs that can’t absorb new parts quickly fall behind. Open architectures offer a practical way to keep pace: design the system so components can be swapped, upgraded, and reused with minimal rework. That idea sounds simple; doing it well takes forethought, standards discipline, and a focus on interfaces over implementations.
